I have found a few more pieces on ebay.com that have the original boxes with Michio Suzuki and also a Lefton ceramic dish which is backstamped with his name.I don't want to keep loading your thread with ebay items - but if it is of any use to your hunt, I will gladly do so. I am looking in other places too for the company. Is it possible he as a Japanese/American? working for Lefton .............. just a thought as his designs appear on their ceramics too.

As mentioned before, I did find a piece of Lefton china and the seller says it is backstamped with the designers name (Michio Suzuki) and I am wondering if the hunt for him would actually lead to the glass factories used by Lefton. I am thinking MS seems linked to Lefton as a designer only and his designs were used on both china and glass.I may be way out but I have included the link to the china that cites MS too.
